Fair Market Value of Stock

How to determine fair market value
for stock received as compensation.

Many of the rules for employee compensation refer to the fair market value of
stock. There's a classical definition of this term that many tax professionals
know by heart:

The fair market value is the price at which
the property would change hands between a willing buyer and a
willing seller, neither being under any compulsion to buy or to
sell and both having reasonable knowledge of relevant facts.

This definition takes you a good part of the way toward understanding the
concept. To complete the picture we'll discuss the following topics:

Valuing publicly traded stock

Stock is publicly traded if you can buy or sell it on an
established securities market, or through some other system that
acts as the equivalent of a securities market. In general the
stock market determines the value of publicly traded stock. The
usual rule is that the value on any given day is the average of
the high and low selling prices on that day.

Employers sometimes use variations on this rule. If the stock
is very thinly traded, it may make sense to use an average over
a period of several trading days so that a single transaction
won't have undue effect on the value. We don't see the IRS
challenging reasonable variations unless they provide
opportunities for manipulation.

It's somewhat unusual, but not impossible, for publicly
traded stock to qualify for a blockage discount as explained
below.

Privately held stock

If your stock isn't publicly traded as explained above, it's
privately held. A full discussion of valuation for privately
held stock is beyond our scope — there are entire books written
on the subject. Here are some of the main points:

Recent transactions

The strongest indication of the value of stock on a given
date is an actual arm's length sale occurring near that date. A
sale is at arm's length if there isn't any family or other
relationship between the buyer and seller that might lead to a
sale at a price different than fair market value. If you want to
claim that your stock has a value of $10 per share, you'll have
a hard time supporting that claim if someone recently paid $50
per share.

Other valuation methods

Sometimes there are no recent sales that can be used to
establish the value of stock. Then you have to estimate the
value of the entire company and divide by the number of shares
outstanding to find the value per share.

Different valuation methods are appropriate for different
types of businesses. Most focus in some way on profits (or an
element of revenues that should be indicative of profit
potential), but the value of the company's assets may come into
play also. The book value of a company (the value of its assets
minus its liabilities, as shown on the company's financial
records) is sometimes seen as a minimum value the company must
have, but some companies have a value that far exceeds book
value.

Inevitably there's an element of subjectivity in determining
the fair market value of a closely held business. As a result,
taxpayers frequently find themselves in court with the IRS over
valuation issues.

Effect of Restrictions

You may feel that restrictions on the stock you acquired make
it less valuable than it would otherwise be. But there's a
special rule here: when you determine the value of your shares,
you have to ignore all restrictions except ones that are
permanent. If your stock is restricted for a limited period of
time, or until some event occurs, you have to ignore the
restriction when you determine the value of the stock.

Discounts

There are circumstances that can justify a discount in the
value of your stock. One recognized discount applies when
there's no market for the stock: a discount for lack of
marketability. Another discount can apply where there's a market
for the stock, but the size of your holdings is large enough to
make efficient sale impossible: a blockage discount. The
availability of these discounts, and the appropriate size of the
discount, should be determined by a qualified appraiser or tax
professional.
